That is in the nature of many GUI systems - "show" asks for the widget to be shown and returns. The fact that "show" has returned does not, however, guarantee that the widget is actually mapped onto the display yet, which is probably the issue you are hitting. There are a few things you could try that might help: - calling Fl::check(); after the show might help get the window mapped... Maybe even call it a few times just to be on the safe side! - you might try calling piano->shown(); to see if it is shown, but I don't believe that reliably tells you if the window is mapped or not. - You could show all your widgets, wait for short while then hope for the best! - Wild guessing time: I don't know your implementation, but maybe you can make the widgets less sensitive to whether they are mapped or not by use absolute co-ords rather than relative co-ords? E.g. based on event_x_root() rather than on event_x()? Any use? -- Ian _______________________________________________ fltk mailing list [email protected] http://lists.easysw.com/mailman/listinfo/fltk
